| Abstract | ||||
| Positioning is very important worldwide in several fields, and it can be deter-mined by several ways. The most popular ways are Global Navigation Satellite Sys-tem (GNSS) and Inertial Navigation Systems (INS). Both techniques have advantages and disadvantages. Accurate positioning is one of the privileges of GNSS, while INS overtops in indoor places, despite low accuracy after long duration. Sensibility to interference and multipath are the principal downsides of GNSS structure, which might be the two primary assets of mistakes in position estimations. The main impact of interference at (GNSS) re-ceiver, consequently dropping its cap potential to navigate, is that it lessens the signal to noise ratio (SNR) of navigational signal such that the receiver is not able to reap measure-ments from the satellite. A comprehensive survey of interference suppression methods is presented in this paper and the interference suppression techniques are compared. Two new recommended filter designs to detect spoofing and optimize acquisition in the pres-ence of interference are proposed. | ||||
